I have several Harveys, their slender bulk is vey appealing. The superwalkers do only cover a small area. Harvey's range has expanded greatly in recent years. I came across C2C walkers who had the durability problem, I have never had problems and it would be great if OS decided to use similar media rather than the bulky lamination available from third parties.
To return to the AA thread, I am very excited about the rejigging of the areas covered by the 1:25,000 green series. My Central Peak District AA walkers has just arrived, and will be great in Hathersage and Castleton. The centre cut is through Grindleford, so you can't please everyone. I do feel that that walkers should make a point of checking these maps out, they are excellent value; today's arrival was £5.99 incl p&p online, an inexpensive way of updating my paper maps
